BELT-FASTENER.

SPECIFICATION forming part of Letters Patent No. 305,540, datedSeptember 23, 1884.

I Application tiled January 0, 1884. (No model.) i I To all whom it mayconcern:

Be it known that I, GEORGE W. SOUTH- WIOK, of Southwick, in the countyof Hampden and State of Massachusetts, have invented a new and ImprovedBelt-Fastener, of which the following is a full, clear, and exactdescription.

The object of my invention is to provide a new and improvedbelt-fastener for uniting the ends of driving-belts, which fastener canalso be used for re-enforcing the belts in case they begin to tear atthe joint.

The invention consists in the construction and arrangement of parts, aswill be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 is a plan View of my improved beltfastener, showing the mannerin which it is used. Fig. 2 is a transverse sectional elevation of thesame on the line m 00, Fig. 1. Fig. 3 is a crosssectionalelevation ofthe same on the line u y, Fig. 1.

The plate A is provided on each longitudinal edge with a series ofdovetail tenons or teeth, B, between which dovetail notches O, ofthesame size as the teeth ortenons B, are formed. Two flat tapered teeth orprongs, D, parallel with the longitudinal axis of the plate A, projectdownward from each dovetail tenon B, at short distance from the endedge, the outer edges of the teeth D being flush with the side edges ofthe dovetail tenons. A round prong or tooth,E,projects downward fromeach dovetailed tenon at its inner end, and at that point at which thesaid prong E projects from each tenon the said tenon is re-enforced by aprojection. F, on the upper surface. A row of round prongs or teeth, G,projects from the under side of the plate A a short distance back of theteeth E. The teeth D, E, and G are not on the same transverse lines ofthe plate, but both halves of the plate A are formed in the mannerdescribed,and as shown in Fig. 1. The plate Ais placed on the outersurface of the belt at the meeting ends of the same, and the teeth orprongs D, E, and G are the other edge being forced into the other end.The ends of the prongs orteeth are then clinched. worn, it is very aptto become ripped by the teeth. In such cases another plate A is secured0n the belt, as shown in dotted lines in Fig. 1, the dovetailed tenonsof the latter plate passing into the dovetailed notches of the platealready on the belt and being guided by the edges of the teeth D. Thenew plate is held on the belt by its prongs, and is connected with theold plate by the dovetailed tenons. The strain will thus be transmittedby the dovetailed tenons to that part of the belt that is not worn andripped. The dovetail tenons permit the plates to bend while passingpulleys, &c.

By means of my improved belt-fastener the belt can be re-enforcedreadily, and need not be adjusted and tightened as often as when theusual lacing, &c. are used, and the belt does not wear out so rapidly.

Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is-

1. A plate, A, provided 011 one or more edges with dovetailed tenons B,from the under outer edges of which project two teeth, and from theinner under side of each of which projects a tooth, E, and are-enforcing projection on the upper side of the tenons or plate abovesaid teeth E, in combinationwith a correspondingly mortised and toothedplate, substantially as set forth.

2. A belt-fastener consisting of the toothed plate A, provided withdovetailed tenons and inortises B O on one or more of its edges, wherebya similarly tenoned, mortised, and toothed plate may be connected withsaid plates A should the ends of the belt break or tear loose therefrom,substantially as shown and described.
